Subject: [GIT PULL] clocksource: event stream on architected timers and
tcb_clksrc misc changes
Message-ID: <5252C443.9070501@linaro.org>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org
Hi Thomas, Ingo,
- Will Deacon and Sudeep KarkadaNagesha implemented the event stream for
architected timer. The event streams can be used to impose a timeout on
a wfe, to safeguard against any programming error in case an expected
event is not generated or even to implement wfe-based timeouts for
userspace locking implementations. Some files fall under the arm
maintainers' umbrella but those changes have been reviewed and acked by
the relevant people (Catalin Marinas and Olof Johansson).
- Boris Brezillon improved the tcb_clksrc driver by removing a
deprecated flag, checking return code values and using functions from
the common clock framework.
Thanks !
